In gram-negative bacteria, the cell wall is thin and releases the dye readily when washed with an alcohol or acetone solution. Cytoplasm-The cytoplasm, or protoplasm, of bacterial cells is where the functions for cell growth, metabolism, and replication are carried out.
Function of the Amygdala. 1  Such spectacular demonstrations may be misleading. Stimulation of the amygdala sometimes triggers violence, but apparently it does not always or even typically trigger violence. 2  When the amygdala is damaged in humans, they lose their sensitivity to stimuli associated with strong emotions.
In MSA, cells are damaged in different areas of the brain which control a variety of body functions. The three areas affected are the basal ganglia, cerebellum and brain stem. In MSA, brain cells in the affected areas shrink (atrophy). This can sometimes be seen on MRI scans. When brain tissue is examined under a microscope, structures called glial inclusion bodies can be seen; they contain a protein called alpha-synuclein.
